According to ChainCatcher, Austin Federa, head of strategy at the Solana Foundation, said Solana will introduce three new mechanisms to increase the priority of transactions, thereby alleviating network congestion. These three mechanisms are:
Priority Fees: used when computing resources/transaction packaging becomes a bottleneck. It is essentially similar to the practice of other blockchain networks to increase gas fees and has global properties.
Local Fee Markets: used to address bottlenecks that occur when multiple people compete for the same state resources at the same time, and have local properties.
Stake Weighted QoS: A screening mechanism for Sybil attacks and spam transactions, which can be used in combination with the first two mechanisms or alone and has global properties.
Federa emphasized that on Solana, these three functions are not mutually exclusive, but provide a flexible and diverse choice for validator nodes. Validators can use different combinations to achieve similar goals based on their own configuration, priorities, and specific circumstances.
In addition, there are some other non-protocol layer solutions, such as MEV relayers, etc. The V0.5 version currently being deployed will undoubtedly bring some externalities that need to be resolved through protocol governance over time.
However, Federa believes that it is better to launch new features as soon as possible and make adjustments after obtaining real data. Federa also specifically clarified that this update does not change the cost of running a validator node, the required stake (still 1 SOL), the threshold for participating in verification (still permissionless), and the basic fees and rewards available to validators.
